' To all ohomz't may concern:

Be it known that I, EDWARD lV. HILL citizen of the Unite l. States of America, re siding at Chica'go; Illinois, have invented a new and useful Sheet-Edge Protector, of which the following is a specification My present invention has for its objects t v rotect the perforated edge portions of the eaves used 1n loose leaf books and particularly to revent the tearing of such edge portions when inserting the leaves in type Writer and such other machines.

i In the accomplishment of the foregoing I provide a suitable backing sheet. for the leaf to be protected and a nerd strip flexibly connected with the bar: ing sheet and dis- 'posed so as to overlie and proteot the per torated edge portion of the leaf,

typewriter .m achin Another feature .15 the provision or": means for gaging the leaf as it is inserted in the protector.

Other features of the invention will appear as the specification proceeds, attention beino directed to the accompanying dravw ing orming a part hereof and wherein l have illustrated "the invention embodied in a practical commercial form.

In said drawing:

Figure 1, is a fragmentary perspective View showing the invention as in. use for protecting a loose ledger sheet insertedin Fig. 2, is a 1 showing the go protective peel .on on the leaf, in dotted lines.

- gin thereof to fit the binding poets of 40 on the plane f the line 3 -6 of 1* Fig. 3, is broken enlarged sectional v' of the protector as in use, taken. *uhstantiaiiv In the illustration 1. have show led er leaf. 5 of t'yplcal construction spit openm e 6 1nthe vertieal side ordinary hinder. 'Great d1fiicul'ty has heretofore been, ex-

l-perienced in handling these leaves in type-- writer machines for the reason that the tongues, provided by the split openings in the edge of the sheet naturally catch on the paper guides, scale,.l1ne gages and otl' er elee- ,ments of the typewriter causing tearing of the marginalportion of the'leaves and there by ruining the leaves for binding ,dpnrposes.

-Te overconiethis I have provl guard s! ed the re teeter here disolosed, comprising-a' ibae 'ng sheet '1 zong whieh the leaf is superposed and hitting a guard strip 8 fiexroly attached.

thereto and arranged to overlie the vertical I side edge of the leaf in which the binding perforations are located. This guard strip may conveniently be formed an integral portion of the hacking sheet, it being herein shown flexibly hinged to the edge portion of the hacking sheet along the line 9 and detaohed from the sheet for the balance of its length as indicated at 10 In use the leaf is placed on the backing sheet with its performed overlying the edge portion of the hacking sheet and the is folded ver so to cover the poi-for ed oi the sheet, substantially Fig. The go i edge the loaf l "lily through the 313$" strip The rip being free for a greater length adjusts itself autoll 5 in going through the machine and L creasing or folding of either.
